The Servo 3 is a tone enhancer pedal from Taurus Pedals, hand-made in Poland. Although it could be described as a boost pedal, Delicious Audio's Paolo De Gregorio notes that it is "certainly NOT a clean type of boost": instead of simply lifting the signal, it is built to sweeten the tone with added volume and harmonic content1.
What it does
The core of the circuit is the Servo Gain knob, which is designed to sweeten your tone with extra volume and harmonic content. Players looking for a transparent volume lift will find this pedal behaves differently: it shapes the sound as it boosts it, sitting closer in spirit to the colored end of the boost and overdrive field than to a clean line booster1.
V3 also carries a Nano Tube, visible through a little crated window, which the maker says adds some extra character to the circuit1.
Controls and switching
- Servo Gain: the core of the circuit, sweetening the tone with extra volume and harmonic content1
- Left footswitch: triggers the boost without affecting the other effects1
The footswitch-triggered boost is an improved function from the toggle switch used in V1 and V2 of the Servo, so the boost can be engaged on its own while the rest of the pedal's effect stays untouched1.
The Servo 3 can run at 9V or 12V, with 12V giving extra headroom. The enclosure is slightly wider than the original Servo1.
Versions
| Version | Boost switching | Notes |
|---|---|---|
| V1 and V2 | Toggle switch | Original enclosure width |
| V3 (Servo 3) | Left footswitch, does not affect the other effects | Nano Tube visible through a crated window, slightly wider enclosure, runs at 9V or 12V1 |

Questions
Is the Servo 3 a clean boost?
Delicious Audio describes it as a tone enhancer that could be described as a boost pedal, but notes it is certainly not a clean type of boost. The Servo Gain knob, the core of the circuit, is designed to sweeten your tone with extra volume and harmonic content, so it colors the signal as it lifts it.
What is new in the Servo 3 compared with earlier versions?
V3 adds a Nano Tube, visible through a little crated window, which adds some extra character to the circuit. The boost can now be triggered by the left footswitch without affecting the other effects, an improved function from the toggle switch used in V1 and V2, and the enclosure is slightly wider than the original.
